I'm sure that Mary Elizabeth was a sibling of George! She can be found on the 1861 census living with 3 unmarried aunts in Wisbech St Peter, surname Soulden.They were called Mary Ann, Milliner, and Sarah and Susan, straw bonnet makers. Mary Elizabeth was 6 years old, born Antwerp.It is quite early in the morning, when I've got my head together I will look up the files and contact you. I remember getting further back than that, and there are some photos.
